Frequency Set
Set the operating frequency of the CPU. The setting
value must be calculated as the following methods.
1. The operating frequency which is shown in MHz units
2. The centuplicated value is converted to the binary

(general register R4). For example, when the
operating frequency of the CPU is 28.882 MHz, the
value is as follows.
